Air Sok's Blog

As my control technology class is nearing its end, this will be my final blog to my readers.This last blog will consist of three parts I will do during the week which evaluates all the sections of work I did this semester. Thank you for reading.

EVALUATION OF SUGAR Q&AALL QUESTIONS AND ANSWERS ON BLOG

PART ONE: WHAT WE DID

1) Rate each of the following out of 5:Guest speaker: Rosemary about Timor Leste 5/5Guest speak: Joel about the xo 5/5Physics 3/5SVG icon and Linux command line 4/5Turtle Art 3/5Other activity evaluation 4/5Etoys 4/5Scratch 4/5

2) Now write aboutThree things that you learnt:1- I learnt that there are many organisations in the world supporting and assisting the one laptop per child goal and I hope that someday I will be able to assist as well.

2- By talking to Joel I was able to learn what courses and skills I need to become an engineer in the future. I have been able to take his advice and adapt it in to my course selection for Year 11.

3- Linux is a great alternative to the common Windows operating system because it is an open source operating system which is completely free and offers free software as good as its proprietry competitors.

Three things that you enjoyed:1- I really enjoyed using the Turtle Art activity because it offered challenging tasks that took me awhile to think of a solution. The patterns I created were very cool and I liked making them.

2- I enjoyed using the linux command line to change icons in Sugar because I am fond of using the terminal/command prompt in operating systems as it seems more efficient then the GUI method of doing things.

3- I also enjoyed listening to the guest speakers as I am pleased to hear that people are helping others in the world by introducing undefunded people to the world of technology and computing. Computers are a great tool in the world and I believe that everyone should be able to use one.

Three things that you didn’t like:

I generally did not like any of the things that we did during the semester. I did get bored of some tasks that took very long to do but I found them all fun to do.

3) State which was the following with reasons:Best - The best thing we did this semester was probably using Turtle Art because I found it very fun to make the interesting patterns.Worst - The worst thing we did this semester in my opinion was using Scratch because I found it a bit too basic compared to the other scripting programs we used.Most interesting - The most interesting thing we did this semester was listening to the guest speakers because I learn alot about organisations and how much they help underdeveloped countries.Most difficult - The most difficult thing I did this was do hard tasks in eToys. I found this the most difficult due to the complicated layout which delayed the time I was able to find commands to script my activity

4) XOIs the xo or olpc a good idea for the children of the developing world? State your opinion and give reasons

I think the XO is an excellent idea because I believe every child deserves the benefit of technology and it is a great resource to teach children who attend underfunded schools. The inexpensiveness of the XO and the range of activities it offers is fantastic for countries such as Timor Leste as I can see they would benefit a lot from the XO.

PART TWO: USER INTERFACEComplete a variety of labelled screenshots which illustrate the differences between these user interfaces

The reason that I like the Linux command line the best is because you can type exactly what you need straight away. Unlike GUI's which make you search for the thing you want, the Linux command line does exactly you want it to because you are in complete control.

I chose the WIMP layout as second preference because I find it very easy to use and the layout is very simple for any one to use.

I chose the Ribbon layout as third preference because it is very similar to the WIMP interface but I find it a bit confusing in term of how it is organised and displayed. This could just be because of the fact that i'm not used to this interface but for now I still prefer the WIMP interface just that bit more.

The reason I chose the Sugar OS Frame interface as my last preference is because I dont like to put my cursor on the edge of the screen everytime I need to change to something else. I like to have menu bars on the screen at all times because I find it a lot more efficient when you are working fast then using the frame interface.

PART THREE: THE FUTUREHave a look at this site which talks about the future of UI: http://nooface.net/3Dimmersive cavesmall screen (iphone)ZUI zooming user interfacemulti touchdigital media you can wear

What will the UI look like when you are 30 years old?DRAW AN ANNOTATED DIAGRAM USING YOUR IMAGINATION AND KNOWLEDGE

I believe that in 15 years we will be using multiple monitors to display information and a massive multitouch desk that will allow us to use our icons and applications through the use of holograms. Keyboards and mice will not be existant anymore because we will be using multitouch and voice recognition to control everything.

This is now the end of my final blog. Thank you to everyone that has helped me out during this semester of Control Technology and thank you to all my fellow bloggers and readers.

Superbrain is a variation of the popular game “Mastermind”. The aim of this activity is to figure out the code that the game has chosen using hints given after submitting a configuration. The code is simple a configuration of coloured balls in a line. If you choose a harder level, the length of the code will be longer and harder to discover. During the game you are given hints after each code submission to assist you. A black ball says that one of the coloured balls are the right colour and in the right position. A white ball says that one of coloured balls is the right colour but in the wrong position.

After playing this game I think that this would be suitable for all ages because I believe that anyone would be able to play this game and enjoy it. It is a good challenge for the brain and helps you learn to think logically.

Negatives:· Activity graphics could be improved· Not enough levels· A timer could be added to have a leaderboard

This activity teaches you to think logically by using the hints given to decipher the configuration of the colour ball code. Training this skill will allow you to work effectively with occurrences which require you to do some problem solving.

Using the Etoys activity on the Sugar OS our control technology class was given tasks to complete using elements of the program such as scripting, variables and drawing.

My favourite task was one referred to as "The Great Race".

The task required us to create a project that allowed 4 race cars to race around a track with various bends using variable speeds to vary the outcome of the race, a timer to time the winning car's speed, and start and reset buttons to initiate the race.

The images shown above show some of the scripts that I made to enable my project to work. The two scripts shown on the left and middle show the scripts that I made for the start and reset buttons. As you can see one starts all the cars scripts to start the race and the other sends all the cars back to their starting positions. The script on the right show how I made my cars run around the track. The car's script uses a simple two colour technique to turn around the track, when the car touches the colour on its left its script will turn right by 25 and if it touches the colour on its right it will turn -20.

I did not encounter any problems during this task as the previous tasks taught me all the techniques that I needed to make this race work correctly.

Today in our control technology class we were given the task to create a svg image for our Sugar OS using HTML Kit.

To create a svg we needed to use graph paper to find x and y co-ordinate points to create the image we desired. I chose to make a smiley face to replace my XO icon on Sugar. We were given a tutorial document so we could understand the basics of using HTML codes. I found it easy because I have done HTML coding before and already understood some of the basics.Here is an image of the svg I made using HTML kit.

The next task we had to do was to replace the original XO icon with the svg image that we made on HTML kit. Once again we were given a document to show us how to do this. It consisted of using Terminal, Vi editor and basic commands such as rm, cp and mv. It was rather easy again for me again because I have worked with Linux terminals previously to set up some other things.Here is a screenshot of my svg in the Sugar OS.I found this activity good because it taught everyone basic commands in Terminal and how to create your own svg using basic co-ordinates and html coding.

Our control technology class was told about a competition the teacher was holding to see who could create the best game using the physics activity on Sugar.

The class was told to break up in to small groups and work together to construct a fun and simple game using physics. My group consisted of three members and we all worked on one computer to make the game.

The idea for our game was to throw the ball over the wall and try to get the highest score. The player gets three throws and can use a ball of any size. After the three throws, the balls scores are added up and the player receives their total score. When everyone has had their turn, the person with the highest score wins!

On the 5th of August 2009, our control technology class met another guest speaker. This guest speakers name is Joel Stanley. He is a electrical engineer who is still learning at the University of Adelaide.

Rather then the usual speeches that guest speakers give, Joel Stanley decided to turn it into a Q&A session to give us the chance to find out what ever we wanted to find out from him.

Here is a list of Q&A's that were asked to Joel Stanley:

What do you do?

I am currently a student at the University of Adelaide studying Electrical Engineering or also known as Computer Systems Engineering

How did you decide to learn engineering at university?

I decided in Year 10 when I went on a camp which showed us all the campuses in the University.

What is your relation with the XO machines?

For ten weeks I was assigned to test what temperatures the XO's could handle without damaging the hardware. I did this by purchasing a pie warmer and boiling water in there with several XO's on the racks. We tested the XO's at 65 degrees Celcius and discovered that they were still 100% operational. I was also assigned to test several XO's using machines to find out which hardware component used the most power. I also had to make sure that the same amount of power usage matched the amount of AC flow that was coming in and figure out how to make the power usage as low as possible.

What was the most power hungry component in the XO?

The display is generally the most power hungry component in laptops and then the CPU comes second.

What are the maps and arrows shown on the projector?

There are three maps. This map shows where the XO is being distributed to and/or tested with children around the world. This other map shows where Masachusetts is. For three months I had an internship at MIT ( Massachusetts Institute of Technology) to work with many other very smart engineers on the XO. This last map shows where Romania is. I flew to Romania to talk to the local children about the XO to explain why the XO's exist and why they are so good for them. I learnt that alot of them havent heard of Linux and that the country is Microsoft exclusive because Mac is simply too expensive for them.

Did you like going to MIT to learn?

I found it very enjoyable because it wasnt really like a job and I had a lot of fun. I got to work with many smart people in America on a really cool project. It was great to know that your working to help children and helping them change their lives for the better.

Do you prefer Microsoft or Linux?

Linux because I support open source software and Windows really annoys me.

Are all XO's Tested before distribution?

About 1 in 1000 XO's are tested to ensure that the day's production has no defects. There is always the case that there are some defects that aren't found because we would have to pay people to check every single XO which is alot of money.

Who makes the XO's?

The assembly line is Taiwan, where women assemble each XO by hand. The leaders of the LPC (Wearing yellow hats) project such as Mary Lou Jepson and Richard Smith, watch over the workers to make sure everything is right. Mary Lou Jepson was the woman who designed the screen which is being used in all the XO systems and Richard Smith worked on the hardware and low level parts of the machine

Is it easy to fix an XO?

Yes it is because there are only three main components: the motherboard, screen and casing which only has eight screws. When I was in America, I was asked to teach a ten year old to take apart an XO and assemble it. The next day I met two children aged ten and eight who could only speak French. I did not explain to the children step by step how to assemble the XO but rather showed them a Wikipage with images to follow. The two children were able to take apart the XO and assemble it back together in only thirty minutes. I made a youtube video about these children and it proved to be very popular around the world.

What other projects are you doing?

I am currently working with the Google Summer of Code. I am working on the Google Chrome browser to help develop it and make it work on Linux

Will XO's be available in shops?

No because the XO is aimed to be a low budget project with the main purpose to assist children in third world countries to learn. If we were to sell XO's in shops it would cost alot of money due to all the marketing which would need to be done such as advertising and making it known.

In this activity you have to select a square labelled "1" and then select a corresponding square labelled "2". If you get the equation correct the two squares will light up yellow. If the equation is incorrect the two squares will flip back and you will have to try again. The aim of the activity is to learn equations and to practice memorising positions and numbers.

In addition, you can change the squares to show letters and play sounds if you get bored of numbers

I find this game somewhat entertaining but think it would be more amusing and beneficial for younger children who are beginning to learn mathematics and memory.
